I just got back from Allen Park where the Detroit Lions had their final OTA. It was fairly uneventful, though neither wide receiver Calvin Johnson nor recently signed offensive lineman Jon Jansen participated.

Here are some notes from the OTA:

• Before anyone freaks out, there's nothing wrong with Johnson. The Lions' star was not at the voluntary camp, but notified the team nonetheless.

• Jansen, who was cut by the Washington Redskins, had to take his physical. By the time he passed, it was too late to participate in practice. He did speak with the media afterward, though; check back for some video of the former Michigan Wolverines tackle.

• Rookie tight end Brandon Pettigrew fought off a couple of defenders to catch a fantastic 30-yard strike from quarterback Matthew Stafford.

• Rookie linebacker DeAndre Levy got into a little skirmish with center Dan Gerberry, a rookie free agent out of Ball State. Nothing major ... just a couple of slaps from first-year players. It was broken up within seconds.

• Linebackers Julian Peterson (Michigan State) and Larry Foote (Michigan) seem to be pretty chummy for college rivals. Now that they're both Lions, the two were chatting it up during linebacker drills.

• Later in practice, Levy and Peterson showed their athleticism by jumping in front of Stafford passes for an interception and to knock down a pass. The rest of the defense roared in approval.

• Linebacker Cody Spencer struggled with the blocking dummy a few times. Eventually, he got the push that LB coach Matt Burke was looking for, but not before the rest of the linebacking crew was able to get in a few jabs.
